Description
The function computes sine and cosine of vector elements.
Note that arguments abs(a[i]) ≤ 213 and abs(a[i]) ≤ 216 for single and double precisions respectively are called fast computational path. These are trigonometric function arguments for which VM provides the best possible performance. Avoid arguments that do not belong to the fast computational path in the VM High Accuracy (HA) and Low Accuracy (LA) functions. Alternatively, you can use VM Enhanced Performance (EP) functions that are fast on the entire function domain. However, these functions provide less accuracy.
Argument | Result 1 | Result 2 | VM Error Status | Exception |
---|---|---|---|---|
+0 | +0 | +1 | ||
-0 | -0 | +1 | ||
+∞ | QNAN | QNAN | VML_STATUS_ERRDOM | INVALID |
-∞ | QNAN | QNAN | VML_STATUS_ERRDOM | INVALID |
QNAN | QNAN | QNAN | ||
SNAN | QNAN | QNAN | INVALID |
Specifications for special values of the complex functions are defined according to the following formula
Sin(z) = -i*Sinh(i*z).
